He went round the monuments to revolutionary activities of President Kim Il Sung and leader Kim Jong Il, the room for preserving historic relics and the room dedicated to the history of the complex.

He recalled that the President established the complex in November 1945, with deep insight into the importance of railways as the artery of the country and pilot of the national economy, adding the Workers' Party of Korea is as old as the complex.

He underscored the need for the complex to effectively conduct education through revolutionary relics to help its employees deeply grasp the undying feats performed by the great leaders so that they may successfully play their role of vanguard and standard-bearers in implementing the party policies by giving steady continuity to the proud history and tradition in which they have remained loyal to the party for the past seven decades.

Going round the passenger car shop, science and technology disseminating room, processing shop No. 1, electric cable shop and other places, he learned in detail about the situation of the complex and set forth important tasks to be fulfilled by it.

He gave an instruction for producing more electric locomotives of the new generation on the basis of cutting-edge technology and waging a dynamic drive to develop and produce new underground electric cars of Korean style in the shortest period.

There is no fortress unconquerable for us if the revolutionary stamina of the heroic working class is combined with modern science and technology, he said, underlining the need for the complex to meticulously organize the work for putting production processes on a high CNC and unmanned basis, regularly operating the science and technology disseminating room, giving fuller play to the vitality of the study-while-working educational system and consolidating the foundation of supply service.

In order to more dynamically step up the building of a thriving socialist nation, it is necessary to decisively modernize the railways of the country, he said, calling for modernizing the railways as required by the new century in the spirit of holding in high esteem the great leaders who used to travel by train day and night, prompted by the desire to provide the people with a happy life at an early date. He promised to personally supervise this work and help it make progress.

He stressed the need to conduct the drive for modernizing railways stretching across the country as an important policy issue, push forward it by focusing the efforts of the party and the state on it and buckle down to it in the spirit of breaking ground and thus turn the nation's railways into those to be proud of in the world as early as possible.

He was accompanied by Hwang Pyong So, Pak Pong Ju, Ri Jae Il and Kim Yo Jong.
